Is algebra possible in Java?

[javapenguin]

Is there a way to trick the java code into solving algebra problems, others than for:

ax + b = cx + d; and ax2 + bx + c = 0 ?

There are some private party packages that will evaluate some expressions.
Don't know about simultaneous(??) equations

Google it.

Depends on how much functionality you want in.

For a Linear System of equations, you can easily implement some sort of algorithm to compute a Reduced Row Echelon matrix, or implement an iterative Linear Algebra solver (I put 2 such implementations here), just note that iterative solvers are not always guaranteed to give you the answer if there is one.

For higher-powered algebra calculations, the "easiest" method would be to implement a computer algebra system/solver or CAS (note: this is used extremely lightly. CAS's are extremely difficult to implement well). I believe there is one implementation here in Java, you probably can dig through the source code there.

edit:

Polynomial solvers shouldn't be too difficult to implement, either. Do a google search and you'll probably find some along with algorithms to solve them numerically.
